Abstract

A polyphase assembly for controlling A. C. devices is capable of producing an electrical impedance of a substantial resistive component. The assembly comprises a plurality of windings (4, 6, 8), separate for each phase, wound on and along a single, axially directed core (2). The core is constituted by at least one ferromagnetic body which may be solid or hollow. The thickness of at least the portions of the core covered by the windings, i.e. the diameter of the solid rod, or the thickness of the solid part of the hollow body, is greater than 1.6 mm.
